Abstract (en)
A tire force estimation system (100) includes a sensor (20), a sensor information acquisition unit (31), and a tire force calculator (32). The sensor (20) measures a physical quantity of a tire (10). The sensor information acquisition unit (31) acquires the physical quantity measured by the sensor (20). The tire force calculator (32) includes an arithmetic model (32a) for calculating tire force F based on the physical quantity, and calculates the tire force F by inputting the physical quantity acquired by the sensor information acquisition unit (31) into the arithmetic model (32a).
